Column 1: QSO number
Column 2: QSO name
Column 3: redshift
Column 4: blue apparent magnitude (directly observed or estimated from the observed visual apparent magnitude and the average relation (B-V) as a function of z)
Column 5: Absolute V magnitude (H₀=50 km/s/Mpc, ₀=1)

Column 6: Code defining the original HLQ sample and the method used for image analysis:

*ESO-KP Type=1,22,23 (Visual search), Type=2,21 (PSF subtraction)
* CFHT (Crampton et al. 1992) Type=3 (PSF subtraction)
* CFHT (Yee et al. 1993) Type=4 (Visual search), Type=5 (PSF subtraction)
* NOT (Jaunsen et al. 1995) Type=7,12,13,17 (Visual search), Type=11 (PSF subtraction)
* HST (Maoz et al. 1993) Type=6,8 (Visual search), Type=16 (PSF subtraction)

Column 7: Seeing (arcsec)
Column 8: Lens status: 1=confirmed gravitational lens
Column 9: Number of image(s)
Column 10: Magnitude difference between the lensed images
Column 11: Angular separation between the lensed images (arcsec)
Column 12: "B"=Best, selects the observation with the maximum probability of showing multiple images

GL statistics studies partly based on this sample of HLQs, have been reported by Surdej et al. (1992, 1993), Claeskens et al. (1993, 1996), Claeskens and Surdej (1996, 2000).
